;;; Commentary:
|
||
|
||
;; Sometimes the fastest way to get something done is just to lean on a key;
|
||
;; moving forward through a series of words by leaning on M-f is an example.
|
||
;; But 'forward-page is orthodoxly bound to C-x ], so moving forward through
|
||
;; several pages requires
|
||
;; Loop until desired page is reached:
|
||
;; Hold down control key with left pinkie.
|
||
;; Tap <x>.
|
||
;; Lift left pinkie off control key.
|
||
;; Tap <]>.
|
||
;; This is a pain in the ass.
|
||
|
||
;; This package defines a command that repeats the preceding command,
|
||
;; whatever that was, including its arguments, whatever they were.
|
||
;; This command is connected to the key C-x z.
|
||
;; To repeat the previous command once, type C-x z.
|
||
;; To repeat it a second time immediately after, type just z.
|
||
;; By typing z again and again, you can repeat the command over and over.
|
||
|
||
;; This works correctly inside a keyboard macro as far as recording and
|
||
;; playback go, but `edit-kbd-macro' gets it wrong. That shouldn't really
|
||
;; matter; if you need to edit something like
|
||
;; C-x ] ;; forward-page
|
||
;; C-x z ;; repeat
|
||
;; zz ;; self-insert-command * 2
|
||
;; C-x ;; Control-X-prefix
|
||
;; you can just kill the bogus final 2 lines, then duplicate the repeat line
|
||
;; as many times as it's really needed. Also, `edit-kbd-macro' works
|
||
;; correctly if `repeat' is invoked through a rebinding to a single keystroke
|
||
;; and the global variable repeat-on-final-keystroke is set to a value
|
||
;; that doesn't include that keystroke. For example, the lines
|
||
;; (global-set-key "\C-z" 'repeat)
|
||
;; (setq repeat-on-final-keystroke "z")
|
||
;; in your .emacs would allow `edit-kbd-macro' to work correctly when C-z was
|
||
;; used in a keyboard macro to invoke `repeat', but would still allow C-x z
|
||
;; to be used for `repeat' elsewhere. The real reason for documenting this
|
||
;; isn't that anybody would need it for the `edit-kbd-macro' problem, but
|
||
;; that there might be other unexpected ramifications of re-executing on
|
||
;; repetitions of the final keystroke, and this shows how to do workarounds.
|
||
|
||
;; If the preceding command had a prefix argument, that argument is applied
|
||
;; to the repeat command, unless the repeat command is given a new prefix
|
||
;; argument, in which case it applies that new prefix argument to the
|
||
;; preceding command. This means a key sequence like C-u - C-x C-t can be
|
||
;; repeated. (It shoves the preceding line upward in the buffer.)
|
||
|
||
;; Here are some other key sequences with which repeat might be useful:
|
||
;; C-u - C-t [shove preceding character backward in line]
|
||
;; C-u - M-t [shove preceding word backward in sentence]
|
||
;; C-x ^ enlarge-window [one line] (assuming frame has > 1 window)
|
||
;; C-u - C-x ^ [shrink window one line]
|
||
;; C-x ` next-error
|
||
;; C-u - C-x ` [previous error]
|
||
;; C-x DEL backward-kill-sentence
|
||
;; C-x e call-last-kbd-macro
|
||
;; C-x r i insert-register
|
||
;; C-x r t string-rectangle
|
||
;; C-x TAB indent-rigidly [one character]
|
||
;; C-u - C-x TAB [outdent rigidly one character]
|
||
;; C-x { shrink-window-horizontally

;;;;; ****************** HACKS TO THE REST OF EMACS ******************* ;;;;;
|
||
|
||
;; The basic strategy is to use last-command, a variable built in to Emacs.
|
||
;; There are 2 issues that complicate this strategy. The first is that
|
||
;; last-command is given a bogus value when any kill command is executed;
|
||
;; this is done to make it easy for `yank-pop' to know that it's being invoked
|
||
;; after a kill command. The second is that the meaning of the command is
|
||
;; often altered by the prefix arg, but although Emacs (19.34) has a
|
||
;; builtin prefix-arg specifying the arg for the next command, as well as a
|
||
;; builtin current-prefix-arg, it has no builtin last-prefix-arg.
|
||
|
||
;; There's a builtin (this-command-keys), the return value of which could be
|
||
;; executed with (command-execute), but there's no (last-command-keys).
|
||
;; Using (last-command-keys) if it existed wouldn't be optimal, however,
|
||
;; since it would complicate checking membership in repeat-too-dangerous.
|
||
|
||
;; It would of course be trivial to implement last-prefix-arg &
|
||
;; true-last-command by putting something in post-command-hook, but that
|
||
;; entails a performance hit; the approach taken below avoids that.
|
||
|
||
;; Coping with strings of self-insert commands gets hairy when they interact
|
||
;; with auto-filling. Most problems are eliminated by remembering what we're
|
||
;; self-inserting, so we only need to get it from the undo information once.
|
||
|
||
;; With Emacs 22.2 the variable `last-repeatable-command' stores the
|
||
;; most recently executed command that was not bound to an input event.
|
||
;; `repeat' now repeats that command instead of `real-last-command' to
|
||
;; avoid a "... must be bound to an event with parameters" error.
|
||
|
||
;;;;; *************** ANALOGOUS HACKS TO `repeat' ITSELF **************** ;;;;;
|
||
|
||
;; That mechanism of checking num-input-keys to figure out what's really
|
||
;; going on can be useful to other commands that need to fine-tune their
|
||
;; interaction with repeat. Instead of requiring them to advise repeat, we
|
||
;; can just defvar the value they need here, & setq it in the repeat command:
|
||
|
||
(defvar repeat-num-input-keys-at-repeat -1
|
||
"# key sequences read in Emacs session when `repeat' last invoked.")
|
||
|
||
;; Also, we can assign a name to the test for which that variable is
|
||
;; intended, which thereby documents here how to use it, & makes code that
|
||
;; uses it self-documenting:
|
||
|
||
(defsubst repeat-is-really-this-command ()
|
||
"Return t if this command is happening because user invoked `repeat'.
|
||
Usually, when a command is executing, the Emacs builtin variable
|
||
`this-command' identifies the command the user invoked. Some commands modify
|
||
that variable on the theory they're doing more good than harm; `repeat' does
|
||
that, and usually does do more good than harm. However, like all do-gooders,
|
||
sometimes `repeat' gets surprising results from its altruism. The value of
|
||
this function is always whether the value of `this-command' would've been
|
||
'repeat if `repeat' hadn't modified it."
